MACHINE FOR SPLITTING-AND WINDING PAPER.

SPECIFICATION forming part of Letters Patent No. 567,164, dated September 8, 1896. Application filed October 307 1895. fierial No. 567,398. (No model.)

To a whom it may concern:

Be it known that I, CHARLES ELMER Porn, a citizen of the United States, residing at Lyons Falls, in the county of Lewis and State of New York, have invented a new and useful Machine for Splitting and Winding Paper, of which the following is a specification.

This invention relates to machines for slitting rolls of paper as they come from the mill and winding the strips or fillets into rolls, the two operationsbeing performed simultaneously, and has for its object to attain the desired end in a rapid and satisfactory manner, to make provision for alining the mandrel upon which the fillets or strips are wound with the actuating mechanism, to devise means for positively rotating the cutters from the resistance-roller over which the paper passes from the main roll to the mandrel and which acts in opposition to the said cutters to sustain the strip of paper during the slitting or cutting operation, to provide for gaining ready access to the sheet or strip of paper for splicing in the ev'entof the sheet parting or the main roll paying out before the roll-strips have attained the required size, and, lastly, to improve the general construction of this class of machines whereby their usefulness and effectiveness are enhanced and the parts easily-reached for removing the strip-rolls and placing the parts in operative relation.

Other objects and advantages are contemplated and result from the special organization of the machine, and will become apparent as the details of the latter are fully understood; and to this end the improvement consists, essentially, in certain novel struc-. tural features and combinations of parts which hereinafter will be more particularly described, illustrated, and finally outlined in the subjoined claims.

In the attached drawings, forming a part of this application, is illustrated a machine constructed in accordance with the principles of this invention, although various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, and in said drawings- Figure 1 is a side elevation of the improved machine; Fig. 2, a reverse side View thereof.

Fig. 3 is a top plan view of the same. Fig. 4 is a front view. Fig. 5 represents diiferent views of a cutter. Fig. 6 is adetail View of the resistance or bed roller. Fig. '7 is a detail view of one end of the bed-roller, showing a cutter in operative relation therewith.

The same reference-numerals denote cor-' responding and like parts in all the figures of the drawings, in which 1 indicates the framework for supporting the operating parts, and may be of any desired pattern and shape according to the design and purpose and character of the Work to be performed.

The roll of paper 2 as received from the mill is mounted in open bearings 3, secured to a rear extension 4 of the framework, and

by having the bearings 3 open the journals of the core or mandrel upon which the sheet of paper is wound can easily and quickly be placed in position or removed from the bearings, as will be readily understood. A shaft 5 is mounted in bearings 6 at the front end of the machine and is provided near its ends with radius-arms 7, formed at their outer ends with open bearings 8, which receive the mandrel 9, upon which the strips or fillets of paper are wound immediately after being out. A gear-wheel 10 is secured upon one end of the shaft 5 and meshes with a pinion 11, secured upon a shaft 12 in the rear of the shaft 5, and which is provided with a hand-wheel 13, by means of which the said shaft 12 and the shaft 5 are turned in their bearings when it is required to move the radius-arms 7.-

Standards 14 are secured to the top portion of the framework near the front end thereof and form stops to limit the rearward movement of the radius-arms '7 when moving the latter into an initial position, thereby bringing the mandrel 9 in alinement with the actuating mechanism, whereby itis rotated to wind the strips or fillets of paper thereon. The mandrel 9 is held in the bearings 8 by removable blocks 15, which are fitted into the open ends of the said bearings 8 to close the latter, and which will be displaced automatically when the radius-arms 7 are turned from an upright to a pendent position, thereby facilitating the removal of the mandrel 9 frornthe bearings 8 after the roll-strips have attained the requiredsize. This operation will be clear when it is remembered that the bearings 8 are open. Hence when the arms 7 are caused to assume a pendent position the open bearings will no longer retain the blocks and the mandrel 9, which will fall away therefrom in the manner stated. No injury will result to the rolls, as the latter will come between the side pieces of the frame, and no damage can happen to the mandrel, as the latter leaves the arms before they reach a vertical position by reason of the bearings 8, opening to one side of the arms, the openings tending toward the extremities of the arms. A carriage is slidably mounted upon the framework and comprises similar side brackets or standards 16, to each of which is attached a raclebar 17, which meshes with a corresponding pinion 18 near the end of a transverse shaft 19,- mounted in bearings 20 near the rear end of the frame. The shaft 19 is provided at one end with a hand-wheel 21, by means of which it is turned when it is required to slide or move the carriage upon the frame toward or from the mandrel 9 for any desired purpose. This carriage supports the cutting mechanism and the resistance or bed roller acting in opposition thereto and bears the mechanism by means of which a positive motion is transmitted from the re sistance or bed roller to the cutting mechanism. Arms 22 extend from the brackets 16 and support the set-screws 23, by means of which the relative distance of the cutting mechanism is adjusted with respect to the resistance or bed roller. J am-nuts 24 are mounted upon the set-screws 23 and are adapted to engage with the arms 22 and hold the set-screws in the located position.

A transverse shaft 25 is mounted in bearings at the upper ends of the brackets 16 and is provided at one end with a lever 26 for convenience in turning the shaft 25 in its bearings. Arms 27 project frointhe shaft 25 and have bearings at their free ends, in which is j ournaled the shaft 28, upon which are placed the rotary cutters 29, the latter comprising a split hub 30 and an annular cutter 31. The annular cutters are similarly formed and are dished and are secured to the hub in any desired manner, preferably by means of ma chine-screws 32-, which pass through suitable openings in the cutter and enter threaded openings in the end or side of the hub. Usually three screws will be provided to secure a cutter to its hub, the middle screw being located opposite the split in the hub and the side screws being disposed one upon each side of the said split, as shown most clearly in the left-hand view of Fig. 5, and the openings 33, through which the end screws pass, are elongated so as to admit of the expansion and contraction of the hub when fitting the cutter upon the shaft 28. A

binding-screw 34 connects the separated ends of the hub, and the head thereof fits in a recess 35 in the side of the hub, so as to be out of the way and obtain a uniform bearing,

whereby the separated ends of the hub can be drawn together when it is required to secure the cutter upon the shaft 28 against rotation. It will be understood that the rotary cutters 29 are strung upon the shaft 28, and when it is required to change their relative location the fastening-screws 32, adjacent to the split of the hub, are loosened and the binding-screw 34 of the cutter or cutters to be shifted is turned back, thereby admitting of the cutter being moved upon the shaft 28 to the required position, which when attained is preserved by turning up the binding-screw 34 previously loosened, so as to cause the hub to become contracted and grip the shaft 28 sufficiently tight to prevent the cutter moving thereon, and the screws32 previously loosened are retightened to prevent any possible looseness of the parts. The arms 27 rest upon the set-screws 23, and by adjusting the latter the relative distance between the cutters 29 and the resistance or bed roller 36 can be varied, thereby providing for variations in the size of the cutters 29 and roller 36.

The resistance or bed roller 36 comprises a shaft 37, journaled at or near its ends in bearings provided in the brackets or standards 1G, and paper disks or washers 38, slipped upon the shaft 37 and confined thereon between a collar 39 at one end and a bindingnut 40 at the opposite end, said binding-nut 40 being mounted upon a threaded portion of the shaft 37 and adapted to screw thereon, so as to clamp the paper disks or washers 38 and hold them in proper relation. A washer 41 is interposed between the binding-nut 40 and the adjacent end of the paper disk-body, and is of a size corresponding to the collar 39, which is of a slightly-less diameter than the diameter of the paper disks 38, thereby admitting of the edge portion of the latter being comparatively free so as to yield slightly for the penetration of the edge portion of the rotary cutters without materially injuring or detracting from the effectiveness of the bedroller. A sprocket gear-wheel 42 is keyed upon the projecting end of the shaft 37 and supports a sprocket-chain 43, by means of which motion is transmittedfrom the sprocket-wheel 42 to a sprocket-pinion 44, mounted upon the shaft 25, carrying the gear-wheel 46, which is in mesh with a pinion 47, keyed to the end of the cutter-shaft 28. The sprocketpinion 44 and gear-wheel 46 are connected by a sleeve 45, loosely mounted upon the shaft 25. By this means the motion imparted to the resistance or bed roller 36 is transmitted to the cutting mechanism, and the latter positively operated. It will be seen that the train of gearing is such as to rotate the cutting mechanism at a relatively higher rate of speed than the resistance or bed roller. Hence the slitting or cutting of a sheet of paper is ac complished in a thorough manner and without producing a ragged edge.

The power-driven shaft 48 is located to one side of the machine and is mounted in bean ings at the upper ends of standards 49 and is provided with a band-pulley 50, which is driven from any suitable source of power in any of the usual ways. This power-driven shaft 48 alines with the mandrel 9 when the latter occupies a normal or initial position, and its projecting end 51 is made angular and supports a coupling or clutch sleeve 52, by means of which the shaft 48 and the mandrel are connected together when it is required to positively rotate the mandrel for winding the strips or fillets of paper thereon to form the rolls. The adjacent end of the mandrel is made angular, as shown at 53, to correspond with the angular portion 51 of the shaft 48, and receives the coupling or clutch 52 when the latter is moved to cause the mandrel and shaft 48 to revolve as a unitary part. The coupling 52 is moved in any desired manner, and, as shown, a shipper-lever 54 is employed for the purpose and is fulcrumed to an arm projecting from the inner. standard 49.

\Vhen it is required to cut a roll of paper into ribbons, strips, or fillets, the said roll is mounted in the bearings 3, and the sheet is drawn therefrom, passed beneath a guideroller 55, thence upward and over the resistance or bed roller, and its end portion is secured to the mandrel 9 in any convenient way. The power-driven shaft 48 being coupled to the mandrel substantially as herein stated, the said mandrel is rotated and draws the sheet of paper from the roll 2 and over the resistance or bed roller and imparts a rotary movement to the latter, and this motion is transmitted to the cutting mechanism through the train of gearing herein particularly described, and the rotary cutters resting upon the bed-roller will slit or cut the strip of paper into strips, ribbons, or fillets of the required width, and these strips are wound upon the mandrel, as will be readily understood. It will be understood that the position of the mandrel is fixed by reason of the standards 14 and the coupling of the said mandrel to the power-driven shaft 48. The tension of the paper strip or sheet against the rear side of the bed-roller will hold the latter against the strips or fillets being wound upon the mandrel, and as the diameter of the mandrel increases by reason of the strips or fillets winding thereon the bed-roller will move rearwardly and thereby allow for the increasing of the roll-strips. Should the sheet of paper tear or become broken, the machine is stopped by ungearing the shaft 48 and the mandrel 9, or by stopping the shaft 48 and by manipulating the hand-wheel 21 the carriage can be drawn back, thereby separating the bed-roller and mandrel a sufficient distance to admit of splicing the ends of the sheet, after which the carriage is moved forwardly by operating the hand-wheel 21 until the bed-roller and the mandrel or the rolls thereon come into engagement. After the rolls on the mandrel have attained the required size the machine is stopped and the mandrel is now withdrawn from the rolls and is placed in position in the bearings 8, and

the hand-wheel 13 is manipulated so as to bring the mandrel into its initial or normal position, when the operation just described is repeated. The shaft'5 is operated to move the arms 7 in either direction by means of the hand-wheel 13, as will be readily understood.

Having thus described the invention, what is claimed as new is- 1.
